Guys , yesterday was the last day for practice the race was today. i faced some problems with my ZX-R MkII. I set the slipper loose to make the car easier to drive, but it was wayy too slow, so i figured i set the slipper too loose. i tightened the slipper and tried the car again, this time it was better but still it was kinda slow in top speed, then i noticed something rather odd in the very loose sections. when i punched the gas, it was as if the front wheels were the only ones driven ! no wonder the car was slow to launh of the line. The other problem i had was everytime i took a hard landing the rear hingepins dislodged it self(both of them) from the arm braces , which are original plastic. Keep in mind the arm braces are not cracked or damaged in any way and they are not loose either. Overall the car was ok, but becuase of these 2 reliability issues which i beleive i cant fix on time, i quickly switch back to my optima mid (with full lazer suspension) since i received a replacement aluminium chassis on friday. i am bit perplexed about the front wheels are getting more drive than the rears, because as far as i know the ZX-R does not have a torque splitter ?


The race today went rather ok, in field of 15 cars, mine being the oldest, i qualified 11th, which placed me at the top of the B. I also drove very slowly to avoid accidents and it paid off. Not bad for a 23 year old car. There was another vintage car in the race, a 93 bosscat, which was behind me. In the final the durango i beat in qualifying took the top spot and i ended up second, and the bosscat 3rd.
Question to ask you welshy, are the big bore shocks really that good? The reason i asked is i see all the top guys are using them, all the A finalists, who drove the Kyosho FS2, Durango DEX410,and Yokomo B-Max4, all had big bore shocks. I asked one of the drivers about them and he says it helps with big landlings and also the rough surfaces. I understand you race on smooth turf, but on rough outdoors bumpy conditions, is it worth the money to go big bore? You were right about the 3 racing shocks being inferior to kyosho golds. i switched to golds all around and my MID was easier to drive, but i was still having issues with the bumpy surface with my car bouncing.
i Talked to another durango guy (non sponsored) and he said that he drove a B44.1 and the car was pretty bad on bumpy tracks becuase the suspension isnt up to it. He kept saying how great the durango suspension is compared to the B44.1 (in effect he was also saying it was better than the Lazers). Question is , what is your opnion about the durango suspension system, and is the ZX's suspension just as good on low traction and very bumpy surfaces? When i say bumpy surfaces i mean tree roots, really !

You get peoples opinions all the time. Once you find your set up you will show them what this car is capable of.

I would check your diffs are taught and are not slipping. Slipper if using brushed motor set it so it slips when you hold it down on the surface your racing on where its fighting the slip and its set. If using brushless we havent redesigned the layshafts yet, one for total 4wd and one with one way. The current slipper cant handle the brushless power.

Also check your rear belt as it may have snapped hence why your seeing front wheels rotating more.

Welshy,

I am bored and rc season won't start for a couple of months (no indoor tracks here). How are you doing with your rear gear box? Can I help?

Welshy, the diffs are fine and not slipping for sure. i am using brushless but its only a 10.5T wihtouht boost or turbo, it was pretty mild compared to other cars with their 6.5T motors. in fact i beat a brand new Yokomo B-Max4 at the race becuase my car was simply more controllable. What are your thoughts about the big bore shocks and how to stop bouncing ?
to have a look at the surface of the track, click on this link. You also will spot me in there, just find the guy with the optima mid, and look at my shirt too ! did you notice how the durango arms are angled like a 1940s WWII plane? does it increase the arms travel like the Durango guy said?

Boored. Very bored. I guess I am going to model the A-arms and see how much they are to be made with titanium. Tougher than aluminum and the car might look too blue if I anodized them blue as well.

If you want to you can draw it up. We only need the one full side in 2d cad.

Well what can I say but I drove like a spanner this weekend. The track had a lot less grip than I was expecting and had set both of my cars up for high grip on new carpet, and didnt really work well. I couldnt really be bothered to change my settings so just drove it badly and made 91st out of 140 odd drivers so a bit crap, however wasnt a dissapointment considering how old the car is.

4wd - ok well fronm the very start I had interferance and is really down to the organisers not thinking correctly and instead of leaving me on my preferred frequency they changed it and put it closer to the openents in my race, not bright are they. So from the go I got interferance when the first car took off, when I got underway I was on for a lap time that would have put me bang in the middle of the event with a mid range 12 lapper but on the fourth lap just when i was leading the round I joined the straight and no longer had control over my car so it went flat out into the brick wall at the end of the straight. I didnt break any Kyosho plastic or kevlar item, the only thing that broke was my chassis and top deck and bent my blue alloy rear of the front gearbox pivot block so that was my event finished, and a bit gutted considering I was on the pace for a reasonable finals place. I had to take my ZXS out and bung my stuff in, only to find in the second round my king pins came out and struggled to keep it on the track as it didnt handle with mini pins attached. third round and this time my knuckle arm totally disconnected from the car when I was doing rather well in the round. Fourth I lowered the rear, added my front wishbones with teamline hubs from my ZXR onto my ZXS as that woundnt fall apart and lowered the front. Car went better and I finished but wasnt enough. I also found the diff in the rear had seized (Iit was due a rebuild hence why I had stopped using it) so I took my rear diff out of my ZXR for the finals. I didnt check to see if it was tight enough and in the final I had zero speed and the rear diff slipped big time so game over. Not the best performance I have ever had but I did have fun.

Still I have realised that the ZXR does need the gearbox redesigned as the ZXS had a 4.5 in it and was ballistic down the straight, to give you an idea an oponent in front (who did beat me overall) in my race was over a quarter down the straight with a Predator before I was on there and I not only caught him at the end of the straight but passed him on the corner. The belt didnt snap and I had the slipper clutch tightend right up, and the belt is still going strong so tensioners are now a must and are needed to put this car back into the game.

Bummer, but consider your unfortunate event (wrong setup, frequency, loose diff, etc, etc) and still finish 91st. I think its pretty well done.

I am thinking about Titanium. Alloy may be too soft, it may distort during impact.

Cost of Titanium isn't that much more than Aluminum.

[isobarik]

Got lots of titanium at work ..
its not in sheets

only good for putting in the ladel...( spelling )

But i have an worn RB5 layshaft coming my way the gear is worn but i will have that taken of so i dint think thats an problem. okay i have to get those expensive kyosho slipper plates but atleat im not paying for the layshaft so i will try to make it fit.
